Safety requirements for escalators and moving walks — Part 1: Global essential safety requirements (GESR)
ISO/TS 25740-1:2011: specifies global essential safety requirements (GESRs) for escalators and moving walks, their components and functions, and establishes a system and provides methods for minimizing safety risks that might arise in the course of the operation and use of, or work on, escalators and moving walks. ISO/TS 25740-1:2011 is applicable to escalators and moving walks that are intended to carry persons. ISO/TS 25740-1:2011 does not specifically cover all needs of users with disabilities, nor risks arising from work on escalators and moving walks under construction and during alterations and dismantling, vandalism, and fire in the environment outside the LCU.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
